Emhlabeni wobuchwepheshe othuthukayo, isidingo semishini ye-elekthronikhi emincane, elula, futhi enamandla kakhulu siholele ekwakhiweni kwamabhodi esekethe aphrintiwe ngezigaba eziningi (ama-PCB).Lawa mabhodi wesifunda ayinkimbinkimbi abe yingxenye ebalulekile ye-electronics yesimanje, evumela ukuba benze imisebenzi eyinkimbinkimbi ngokuphumelelayo.Kule bhulogi, sizocubungula ubunkimbinkimbi bama-PCB anezingqimba eziningi futhi sixoxe ngesakhiwo sawo, izinzuzo, kanye nezicelo ezibalulekile ezimbonini ezihlukahlukene.
I-Multilayer PCB, njengoba igama liphakamisa, yakhiwe izendlalelo eziningi zamasekhethi.Ngokungafani nama-PCB avamile anohlangothi olulodwa noma olukabili akwazi ukuphatha kuphela ubunkimbinkimbi besekethe obulinganiselwe, ama-PCB anezingqimba eziningi angakwazi ukwamukela inethiwekhi ebanzi yokulandela umkhondo, uxhumo, nezingxenye.Aqukethe okubalulekile kwe-substrate (ngokuvamile i-FR-4) kanye nezingqimba eziningi zokulandela zethusi ezihlukaniswa izingqimba ezivikelayo.Lezi zingqimba zixhunywe izimbobo ezincane ezibizwa ngokuthi i-vias, okuvumela amasignali namandla ukuthi ageleze phakathi kwezingqimba ezihlukene.
Izinzuzo ze-PCB ye-multilayer:
Inhlanganisela yezendlalelo eziningi ekwakhiweni kwe-PCB inikeza izinzuzo ezimbalwa.Okokuqala, ama-PCB anezingqimba eziningi avumela ukuminyana kwesekethe okuphezulu, awenze alungele amadivayisi kagesi ahlangene njengama-smartphone, amakhompyutha aphathekayo, nezinto ezigqokwayo.Ukwengeza, banikeza ukulawula okungcono kwe-impedance, ukunciphisa ukuphazamiseka nokuthuthukisa ubuqotho besignali.Ama-PCB angama-Multilayer aphinde abe nezakhiwo ezithuthukisiwe zokuqeda ukushisa ngenxa yendawo yawo enkulu, enikela ekupholiseni okuphumelelayo kwezingxenye.Ngaphezu kwalokho, bafaka ukuhambisana okuthuthukisiwe kwe-electromagnetic (EMC), behlisa amandla e-crosstalk futhi baqinisekise ukusebenza okuthembekile.
Izinhlelo zokusebenza ze-PCB enezingqimba eziningi:
Ngenxa yokuguquguquka kwayo kanye nezinzuzo eziningi, ama-PCB amaningi asetshenziswa kakhulu emikhakheni ehlukahlukene.Embonini yezimoto, asetshenziswa ezinhlelweni zokusiza abashayeli (ADAS), amayunithi okulawula injini (ECUs) kanye nezinhlelo ze-infotainment.Imikhakha ye-aerospace neyezokuvikela ithembele kuma-PCB anezingqimba eziningi ukuze aqalise izinhlelo zokuxhumana, ama-radar namasistimu okuzulazula.Emkhakheni wezokwelapha, asetshenziswa emishinini efana nemishini ye-MRI, izikena ze-ultrasound kanye nemishini yokuqapha isiguli.Ukwengeza, ama-PCB anezinhlaka eziningi abalulekile ekuzishintsheni kwezimboni, ezinhlelweni zamandla avuselelekayo, kanye nama-electronics abathengi.
Umbono wekusasa nesiphetho:
Njengoba ubuchwepheshe buqhubeka buthuthuka ngezinga elingakaze libonwe, ama-PCB anezinhlaka eziningi abe yingxenye ebalulekile yomhlaba we-electronics.Njengoba isidingo se-miniaturization kanye nokusebenza okuphezulu siqhubeka nokwanda, indima yama-PCB anezigaba eziningi izoqhubeka nokukhula.Abacwaningi nonjiniyela bayaqhubeka nokuhlola izinto ezintsha nezindlela zokukhiqiza ukuze bathuthukise ukwakheka nokusebenza kwama-PCB anezingqimba eziningi.
Kafushane, ama-PCB anezinhlaka eziningi aguqule imboni yezogesi ngokunikeza ukubumbana, ukusebenza okuthuthukisiwe, nokwethembeka.Benze igalelo elibalulekile ekuthuthukisweni kwemishini ye-elekthronikhi emincane, esebenza kahle kakhulu elololonga impilo yethu yansuku zonke.Njengoba sibhekela emhlabeni ohlakaniphe kakhudlwana, oxhumene kakhulu, ikusasa lama-PCB ahlukahlukene linamandla amakhulu okuthuthukisa intuthuko yezobuchwepheshe.
